7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, just unbuckle the
vehicle’s safety belt and let it go back all the way.
The safety belt will move freely again and be
ready to work for an adult or larger child
passenger.
Airbag System
Your vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.Your vehicle may have the following airbags:
A roof-mounted rollover airbag for the driver
and right front passenger.
A roof-mounted rollover airbag for the second
row outboard passenger positions.
If your vehicle has roof-mounted rollover airbags,
the word AIRBAG will appear on the airbag
covering on the headliner above the sidewall trim
near the driver’s and right front passenger’s
window and the rear passenger’s outboard seating
positions.
Airbags are designed to supplement the protection
provided by safety belts. Even though today’s
airbags are also designed to help reduce the risk
of injury from the force of an in ating bag, all
airbags must in ate very quickly to do their job.

Here are the most important things to know about
the airbag system:
{CAUTION:
You can be severely injured or killed in a
crash if you are not wearing your safety
belt — even if you have airbags. Wearing
your safety belt during a crash helps
reduce your chance of hitting things
inside the vehicle or being ejected from it.
Airbags are “supplemental restraints” to
the safety belts. All airbags are designed
to work with safety belts, but do not
replace them.
{CAUTION:
Frontal airbags for the driver and right
front passenger are designed to deploy in
moderate to severe frontal and near
frontal crashes. They are not designed to
in ate in rollover, rear crashes, or in many
side crashes. And, for some unrestrained
occupants, frontal airbags may provide
less protection in frontal crashes than
more forceful airbags have provided in
the past.
Roof-mounted rollover airbags are
designed to in ate in moderate to severe
crashes where something hits the side of
your vehicle, during a vehicle rollover, or
in a severe frontal impact. They are not
designed to in ate in rear crashes. If your
vehicle has roof-mounted airbags, they
are designed to provide both side impact
protection and rollover protection.
CAUTION: (Continued)

CAUTION: (Continued)
Everyone in your vehicle should wear a
safety belt properly — whether or not
there is an airbag for that person.
{CAUTION:
Both frontal and roof-mounted side impact
airbags in ate with great force, faster than
the blink of an eye. If you are too close to
an in ating airbag, as you would be if you
were leaning forward, it could seriously
injure you. Safety belts help keep you in
position for airbag in ation before and
during a crash. Always wear your safety
belt even with frontal airbags. The driver
should sit as far back as possible while
still maintaining control of the vehicle.
Occupants should not lean on or sleep
against the door.
{CAUTION:
Anyone who is up against, or very close
to, any airbag when it in ates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer the best
protection for adults, but not for young
children and infants. Neither the vehicle’s
safety belt system nor its airbag system is
designed for them. Young children and
infants need the protection that a child
restraint system can provide. Always
secure children properly in your vehicle.
To read how, seeOlder Children on
page 45orInfants and Young Children on
page 48.

The right front passenger’s airbag is in the
instrument panel on the passenger’s side.If your vehicle has a roof-mounted rollover airbag
for the driver and the person seated directly
behind the driver, it is located in the ceiling above
the side windows.

If your vehicle has a roof-mounted rollover airbag
for the right front passenger and the person
directly behind that passenger, it is located in the
ceiling above the side windows.
{CAUTION:
If something is between an occupant and
an airbag, the bag might not in ate
properly or it might force the object into
that person causing severe injury or even
death. The path of an in ating airbag must
be kept clear. Do not put anything
between an occupant and an airbag, and
do not attach or put anything on the
steering wheel hub or on or near any
other airbag covering. And, if your vehicle
has roof-mounted side impact airbags,
never secure anything to the roof of your
vehicle by routing the rope or tie down
through any door or window opening. If
you do, the path of an in ating side
impact airbag will be blocked. The path of
an in ating airbag must be kept clear.

When Should an Airbag In ate?
The driver’s and right front passenger’s frontal
airbags are designed to in ate in moderate to
severe frontal or near-frontal crashes. But they are
designed to in ate only if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds take into account a variety of desired
deployment and non-deployment events and are
used to predict how severe a crash is likely to be in
time for the airbags to in ate and help restrain the
occupants. Whether your frontal airbags will or
should deploy is not based on how fast your vehicle
is traveling. It depends largely on what you hit, the
direction of the impact, and how quickly your
vehicle slows down.
Frontal airbags may in ate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could in ate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could in ate at a different crash
speed than if the vehicle hits an object that
does not deform.
If the vehicle hits a narrow object (like a pole),
the airbags could in ate at a different crash
speed than if the vehicle hits a wide object
(like a wall).
If the vehicle goes into an object at an angle,
the airbags could in ate at a different crash
speed than if the vehicle goes straight into
the object.
Frontal airbags (driver and right front passenger)
are not intended to in ate during vehicle
rollovers, rear impacts, or in many side impacts.
Your vehicle has a seat position sensor which
enables the sensing system to monitor the
fore and aft position of the driver’s seat. Seat
position sensors provide information that is used
to determine if the airbags should deploy at a
reduced level or at full deployment.
Your vehicle may or may not have roof-mounted
rollover airbags and a rollover sensor. See
Airbag System on page 83. These “rollover
capable” airbags are intended to in ate in
moderate to severe side crashes, during a rollover,
or in a severe frontal impact. A roof-mounted
rollover airbag will in ate if the crash severity is
above the system’s designed “threshold level.”
89
Page 90 of 680
The threshold level can vary with speci c vehicle
design. Roof-mounted airbags are not intended
to in ate in rear impacts. Both roof-mounted
rollover airbags will deploy when either side of the
vehicle is struck, during a rollover, or in a
severe frontal impact.
In any particular crash, no one can say whether
an airbag should have in ated simply because
of the damage to a vehicle or because of what the
repair costs were. For frontal airbags, in ation is
determined by what the vehicle hits, the angle
of the impact, and how quickly the vehicle slows
down. For roof-mounted rollover airbags,
in ation is determined by the location and severity
of the impact or a rollover event.
The airbag system is designed to work properly
under a wide range of conditions, including off-road
usage. Observe safe driving speeds, especially
on rough terrain. As always, wear your safety belt.
SeeOff-Road Driving on page 390for tips on
off-road driving.
If the GVWR (Gross Vehicle Weight Rating) of
your vehicle is 8,500 lb (3 855 kg) or above, your
vehicle has single stage airbags. If the GVWR
is below 8,500 lb (3 855 kg), your vehicle has dual
stage airbags. You can nd the GVWR on thecerti cation label on the rear edge of the driver’s
door. SeeLoading Your Vehicle on page 425
for more information.
Single Stage Airbags
If your vehicle has frontal airbags with single stage
deployment and your vehicle goes straight into
a wall that does not move or deform, the threshold
level is about 12 to 16 mph (19 to 26 km/h). The
threshold level can vary, however, with speci c
vehicle design, so that it can be somewhat above
or below this range.
Dual Stage Airbags
If your vehicle has frontal airbags with dual stage
deployment, the amount of restraint will adjust
according to crash severity. Your vehicle has
electronic frontal sensors which help the sensing
system distinguish between a moderate and a
more severe frontal impact. For moderate frontal
impacts, these airbags in ate at a level less
than full deployment. For more severe frontal
impacts, full deployment occurs. If the front of your
vehicle goes straight into a wall that does not
move or deform, the threshold level for the
reduced deployment is about 9 to 16 mph
(14 to 26 km/h), and the threshold level for a full
deployment is about 18 to 23 mph (29 to 37 km/h).
90
Page 91 of 680
The threshold level can vary, however, with
speci c vehicle design, so that it can be somewhat
above or below this range. Vehicle’s with dual
stage airbags also have a sensor which enables
the sensing system to monitor the position of
the driver seat. The seat position sensor provides
information which is used to determine if the
airbags should deploy at a reduced level or at full
deployment.
What Makes an Airbag In ate?
In an impact of sufficient severity, the airbag
sensing system detects that the vehicle is
in a crash. In the case of a roof-mounted rollover
airbag, the sensing system detects that the
vehicle is about to roll over or has been in a severe
frontal impact or a moderate to severe side
impact. The sensing system triggers a release of
gas from the in ator, which in ates the airbag.
The in ator, airbag, and related hardware are all
part of the airbag modules inside the steering
wheel and in the instrument panel in front of the
right front passenger. For vehicles with
roof-mounted rollover airbags, the airbag modules
are located in the ceiling of the vehicle, near
the side windows.
How Does an Airbag Restrain?
In moderate to severe frontal or near frontal
collisions, even belted occupants can contact the
steering wheel or the instrument panel. In
moderate to severe side collisions, even belted
occupants can contact the inside of the vehicle.
Airbags supplement the protection provided
by safety belts. Airbags distribute the force of the
impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But
the frontal airbags would not help you in many
types of collisions, including rollovers, rear
impacts, and many side impacts, primarily because
an occupant’s motion is not toward the airbag.
Roof-mounted rollover airbags would not help you
in many types of collisions, including many
frontal or near frontal collisions, and rear impacts.
Airbags should never be regarded as anything
more than a supplement to safety belts, and then
only in moderate to severe frontal or near-frontal
collisions for the driver’s and right front
passenger’s frontal airbags, and only in moderate
to severe side collisions or rollovers for vehicles
with roof-mounted rollover airbags.

What Will You See After an Airbag
In ates?
After a frontal airbag in ates, it quickly de ates, so
quickly that some people may not even realize
an airbag in ated. Roof-mounted rollover airbags
may still be at least partially in ated minutes
after the vehicle comes to rest. Some components
of the airbag module — the steering wheel hub
for the driver’s airbag, the instrument panel for the
right front passenger’s airbag, and the area
along the ceiling of the vehicle near the side
windows for vehicles with roof–mounted side
impact airbags — may be hot for a short time. The
parts of the airbag that come into contact with
you may be warm, but not too hot to touch. There
may be some smoke and dust coming from the
vents in the de ated airbags. Airbag in ation does
not prevent the driver from seeing out of the
windshield or being able to steer the vehicle, nor
does it prevent people from leaving the vehicle.
{CAUTION:
When an airbag in ates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the vehicle
after an airbag in ates, then get fresh air
by opening a window or a door. If you
experience breathing problems following
an airbag deployment, you should seek
medical attention.
Your vehicle has a feature that may automatically
unlock the doors, turn the interior lamps on,
and ash the hazard warning ashers when the
airbags in ate. You can lock the doors again, turn
the interior lamps off, and turn off the hazard
warning ashers by using the controls for those
features.
